Coming from a background "unbounded" by CS, and more often approaching a mathematical context, the tutorial explanation, and even moreso the comment aftewards, are amazingly AWESOME!
I'm usually left stuck between programmers who dislike math, and mathematicians who just don't get computers, and getting any kind of consensus and mutually beneficial discussion is impossible...
A big thank-you to both authors for your time and effort, and if anyone is aware of additional resources for such topics (CS/math and math/CS crossovers, or explanations of theories behind practical applications and, of particular interest to me, practical applications of theories), PLEase share!

When putting a smiley right before a closing parenthesis, do you:

Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
